7.2.3 Titration parameters
Menu ▶ Parameters ▶ Titration parameters
The parameters that influence the sequence of the entire titration are
defined under Titration parameters.
Solution
Selection of the solution from the solution list. We recommend always
selecting the solution. This ensures that the correct data (titer, concentra-
tion, etc.) is always used for the calculation. Solutions are defined under
System
▶ Solutions.
For buret units with integrated data chip, a check is made in the method
run to verify whether the correct solution has been attached and whether
the type of dosing drive matches. For buret units without integrated data
chip, the cylinder volume and the type of dosing drive are checked. The
validity of the titer is checked for the selected solution at the start of the
determination.
Selection Selection of configured solution | not defined
Default value not defined
not defined
No check takes place.
Sensor
Selection of the sensor from the sensor list. The selection depends on the
measuring mode. Sensors are defined under System
▶ Sensors.
Selection Selection of configured sensors
I(pol)
The polarization current is the current that is applied at a polarizable elec-
trode during the voltametric measurement. This parameter is available
only with I(pol) determinations.
Input range –125 - 125 µA (Increment: 1)
Default value 5 µA
U(pol)
The polarization voltage is the voltage applied to the polarizable electrode
during an amperometric measurement. This parameter is available only
with U(pol) determinations.
Input range –1250 - 1250 mV (Increment: 10)
Default value 400 mV
